SEC's Aguilar says crisis bolstered urgency of market review

Luis Aguilar, a member of the Securities and Exchange Commission, said a review of market structure by financial regulators is an important step. "I think we should have a holistic view of the entire market," Aguilar said. "There are benefits and there are costs to everything that we do. I think the potential benefits of our looking at the market and making sure that it remains efficient, those outweigh the costs."
